Gennaro Gattuso has replaced Carlo Ancelotti as Napoli head coach, the club has confirmed.
Former manager Ancelotti was sacked on Tuesday after 19 months in charge in Naples.
Napoli announced the decision to dismiss Ancelotti an hour after he led the club to the knockout stages of the Champions League with a 4-0 home win against Genk, ending a nine-match run in all competitions without victory.
It was reported on Tuesday that former AC Milan manager Gattuso was the leading candidate to take over at Napoli, and it is understood the 41-year-old has joined on a provisional six-month deal with an option of a further 12 months.
Napoli, who face Parma in their next game on Saturday, are currently seventh in Serie A.
